"She's doing really well," Hawn told PEOPLE at the Partouche Charity Poker Festival in Cannes, where $1 million is up for grabs for a charity of choice. (Celebrity players include Hawn, Woody Harrelson, Dennis Hopper, Salma Hayak, Edward Norton and Tim Robbins.)

Hawn, who is in town for several days before departing on a Tuscan biking trip with partner Kurt Russell, said she hoped to win – as long as she kept her sunglasses on during the nighttime tournament

"My eyes are the window in to my soul and I can't lie. I need them to keep a poker face," said the actress, who was dressed in a plunging Roberto Cavalli gown accompanied by Bulgari jewels.

And how is daughter Kate? "She is amazing," said Hawn. "She is an amazing girl."
